How Tally Health Works
Tally Health’s biological test measures DNA methylation, a chemical modification of DNA that can alter gene expression and influence the production of protein in cells that are essential for functioning. The brand claims that DNA methylation patterns change with age and directly correlate with one’s personal lifestyle habits, including diet, exercise, sleep quality and alcohol consumption. Research shows that genetic factors account for roughly 25% of how we age while lifestyle factors serve as a stronger determinant[1]Passarino G, De Rango F, Montesanto A. Human longevity: Genetics or Lifestyle? It takes two to tango. Immun Ageing. 2016;13:12. .
Tally Health suggests its DNA methylation data set can be used to predict a person’s biological age. The data set includes age ranges 18 to 100, a 50/50 gender split and is over 30% non-white, according to the company.
Generally, Tally Health’s overall system is designed to motivate customers to make wiser lifestyle choices that may promote a longer, healthier life.
The TallyAge test requires customers to take a cheek swab of personal DNA and send it to the company’s lab for testing. The company advises users not to eat or drink at least 30 minutes before taking the test. Once complete, users can simply seal and ship the test to the lab and await their results.
Upon receipt of the test results, users can take Tally Health’s lifestyle survey to gain advice on what lifestyle modifications they should prioritize based on their DNA test and survey results. Tally’s healthy lifestyle recommendations align with what the company believes are keys to healthy aging, such as exercise, better sleep quality, healthy eating and limited alcohol consumption.
Tally Health also provides its daily vitality blend supplement to those who elect to subscribe for a monthly membership plan. The company claims that this supplement can enhance essential functions for cellular energy and repair, which in turn “promotes peak epigenetic function.” The formula includes ingredients with potential anti-aging properties, including alpha-ketoglutarate, quercetin and resveratrol[2]Naeini SH, Mavaddatiyan L, Kalkhoran ZR, Taherkhani S, Talkhabi M. Alpha-ketoglutarate as a potent regulator for lifespan and healthspan: Evidences and perspectives. Experimental Gerontology. 2023;175:112154. [3]Zhou D-D, Luo M, Huang S-Y. Effects and Mechanisms of Resveratrol on Aging and Age-Related Diseases. Oxid Med Cell Longev. 2021;2021:9932218. .
Tally Health’s online portal provides customers with direct access to their TallyAge, the biological age determined by their DNA test.

What Experts Say About Tally Health
Some experts question the validity of biological aging and Tally Health’s usefulness as a resource for healthy aging. In terms of the biological aging theory, New York-based registered dietitian-nutritionist Emily Tills believes it does hold a little weight as a concept. “Those who have been through a lot of physical and psychological stress that has impacted their lifestyle can appear older than their chronological age,” she says. “What we eat and how we take care of ourselves can predict how well we age and our health status.”
However, Illinois-based registered dietitian Sylvia Klinger believes that the concept has some holes. [One’s biological age is] mainly determined by lifestyle, and it takes more than a swab test to help slow the aging process in an effective way. One needs to complete an individualized assessment of their lifestyle and commit to certain changes accordingly.
As far as the TallyAge test and Tally Health’s daily supplement are concerned, Klinger doesn’t think either are necessary for one’s healthy aging journey. “There are better (and less expensive) ways to slow the aging process that don’t require a membership, expensive test or expensive supplements,” she says. “[There also isn’t] sufficient reliable data to prove [the] safety and effectiveness of their supplements.”
Tills raises an additional concern regarding customer support throughout the journey with Tally Health products. “The test is done every three months and vitamins are sent, but there’s minimal information on the website about ongoing support…or counseling…or aid in understanding the labs and what everything means to their day to day life,”she says.
While Tills suggests approaching such DNA tests and unregulated supplements with a healthy dose of skepticism, she does believe that the TallyAge test can help people put into perspective where they are in the aging process based on their current habits and lifestyle choices and what trajectory they’re on in terms of healthy aging. Beyond that benefit, she recommends consulting with a health care provider to learn about any nutritional deficiencies you may have and address them accordingly rather than completely relying on this solution.
The Tally Health Experience
There are no published reviews—for the TallyAge test or vitality blend supplement—on the Tally Health website or Trustpilot. Limited review availability makes the overall user experience unclear for prospective customers before they try it themselves. However, existing Tally Health reviews on YouTube conclude that while the brand’s solutions aren’t a “cure” for aging, they can be useful resources for someone interested in taking steps toward improved longevity.
